Following injection of aequorin into small bundles of rat soleus and extensor digitorum longus muscles, simultaneous measurements of light (proportional to the intracellular free calcium ion concentration ([Ca2+]i)) and force were recorded during muscle twitches over a range of temperatures from 10 to 37 degrees C. The Arrhenius plots for rate of decline of [Ca2+]i following a twitch were linear and yielded the same activation enthalpy (Ea) for both muscle types, indicating that the same process controls Ca2+ uptake in both fast and slow muscles. Arrhenius plots of force decay rate constants showed a break around 20 to 25 degrees C with the Ea's above the break being similar to the Ea's for decline of [Ca2+]i and indicating a close relationship between rate of relaxation and decline of [CA2+]i above this temperature.
